Battery test!

Last night, Jim brought in his battery discharge tester. (Have you been reading his blog? He’s got some great projects!) We hooked it up to my Roomba battery to try to see what cells were bad. (My phone didn’t take the best photo in the light near the computer at the space.) It turns out that the battery had self-discharged enough over the past month since I last had it on the charger that we only got the nominal values for the cells. This is a really cool project that was completely designed and built by one of our own members. How awesome is that?!
